The CLI (Command Line Interface) on routers can be accessed in different ways:
1. Console port: This is a physical port on the router that allows direct connection using a console cable to configure the router through a terminal emulator like PuTTY or SecureCRT.
2. Virtual terminal lines: These are virtual connections that enable remote access to the router's CLI using protocols like Telnet or SSH. By configuring virtual terminal lines, network administrators can remotely manage the router's configuration.
In this context, the USB port is not typically used to access the CLI on routers. The auxiliary port, though present in some routers, is not commonly used for accessing the CLI directly. Therefore, the correct ways to access the CLI on routers are through the console port and virtual terminal lines.
